Break up NSData into byte packets to send to another device

1)How can I break up an NSData into chunks?

I want to iterate through the NSData and send each chunk via sendData GameKit.

2)The data that is being sent is an MP3. When the first chunk comes in, I want to convert it back to an MP3, start playing that file, then keep appending the remaining audio to it. How do I?

For the first the first part of your question...

You can break it up using the getBytes:length: and getBytes:range: instance methods.

Check the reference here.

For the second part of your question...

Use appendData. Of course this method for a NSMutableData. Find the reference here
